FAQ: Pinhole Glasses

The current Dherbs directions recommend continuing to use normal glasses or contact lenses during the rest of the day. Whether pinhole eyewear should be combined directly with your prescription correction depends on your individual visual needs.

Reading glasses use magnifying lenses to assist near vision. Pinhole eyewear uses apertures rather than magnification, so the two products operate according to different optical principles.

Regular prescription glasses use corrective lenses selected according to an individual's refractive error. Pinhole Glasses use small apertures to restrict incoming light and create a temporary optical focusing effect without prescription lenses.

The perforated viewing pattern is very different from conventional transparent lenses. It may take some time for your visual attention to adjust to looking through multiple small openings.

They can affect stereopsis, which contributes to depth perception. Users should therefore avoid activities where accurate judgment of distance is important for safety.

Yes. The opaque portions of the glasses can restrict the visual field, which is an important reason they shouldn't be worn while driving or during other activities requiring full peripheral awareness.

Research has found increased depth of focus while subjects were wearing pinhole glasses. This is one of the established optical effects associated with restricting incoming light through small apertures.

The small apertures reduce the range of light rays entering the eye. This can decrease retinal blur and increase depth of focus, causing certain objects to appear temporarily sharper.

Most of each lens area is opaque, so only a fraction of the available light passes through the perforations. Reduced brightness is therefore an expected characteristic of pinhole eyewear.

No. Pinhole Glasses should not be treated as sunglasses or UV-protective eyewear unless a product has specifically been tested and labeled for that purpose.

Dherbs recommends indoor use and warns against wearing the glasses outside in bright sunlight. They aren't designed to replace appropriate sunglasses.

No. Do not operate machinery while wearing them because unrestricted peripheral vision, contrast sensitivity and depth perception may be necessary for safe operation.

No. Never drive while wearing Pinhole Glasses. Their restricted field of view and effects on contrast and depth perception can interfere with the visual information necessary for safe driving.

No. The product is intended for limited periods rather than continuous everyday vision correction. The restricted light, peripheral vision and contrast make prolonged use inappropriate for many normal activities.

People with myopia may experience temporarily improved distance clarity through pinholes. This doesn't replace appropriate eye examinations or prescribed vision correction.

Pinhole Glasses don't contain prescription corrective lenses, so the product itself doesn't require an individualized eyeglass prescription.

There is not sufficient evidence to claim that wearing pinhole glasses permanently corrects refractive errors. Their immediate improvement in clarity is primarily an optical effect that occurs while viewing through the perforations.

A small opening blocks some of the light rays that would otherwise contribute to blur. This optical phenomenon is commonly known as the pinhole effect.

Each small opening allows a narrow beam of light to enter the eye while blocking many peripheral rays. This can reduce the blur circle on the retina and temporarily make certain objects appear sharper.

Pinhole Glasses are eyewear featuring opaque panels with multiple small perforations instead of conventional transparent lenses. The holes restrict incoming peripheral light and create a temporary pinhole focusing effect.
